Chinese e-commerce retailer Temu has filed a lawsuit in Massachusetts accusing its rival Shein of violating US antitrust law by preventing garment makers from working with it.

Temu, which is owned by popular Chinese e-commerce site Pinduoduo, is alleging that Shein has compelled clothing manufacturers to submit to unfair supply chain arrangements preventing them from working with Temu after it entered the US market in 2022.
